snow GUARD.

Application filed December 2, 1926. Serial No. 152,223.

The invention relates to improvements in snow guards for roofs and has reference more particularly to one designed prii'narily :lor use with shingle roots.

llt is the object or the invention to provide a snow guard of new and improved construction, formed from a single length oi? wire and bent in such a manner as to produce a very rigid and eliiective structure which may be quickly and easily attached.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being slu'iplcmented by the aeron'ip: nying d r a w i n Fig. l is a vertical section through a portion ot a root showing the invention applied thereto.

Fig. 2 is an elevation of the parts shown in Fig. 1 looking .in the direction of the arrow A.

Fig. 3 is an enlarged side elevation oi. the guard. i

Fig. 1- is a top plan view.

Fig. 5 is a transverse sectional view on line oi? Fig. 3.

in cmistructiug the device, I make use of a single le gth of stiil wire having a straight end portion (5 constituting a shank to lie between the edges OIli two adjacent shingles and to be, when applied, interposed between an overlying shingle and an underlying shingle. The wire at the upper end of this shank is bent downwardly and sharpened to provide an attaching shank 7 to be driven into the sheating of the root, and at the lower end of the shank, the wireis bent first upwardly and then downwardly to provide an arched portion 8. From this portion 8, the wire extends in a down-roof direction, on a straight line, forming a base portion 9 to contact with the underlying shingle. At the lower end of this base portion, the wire is bent upwardly at an acute angle to provide a brace 10, and at the upper end of this brace, the wire is curved laterally in one direction and downwardly to provide one- 1 half of an annular snow stop 12, said half being denoted at 11. After forming this half, the wire is coiled tightly around the arched portion 8 as indicated at 13 and from this coil, said wire is curved laterally and upwardly to provide the other half 14 of the stop 12, and the free end 15 of the wire, after forming said stop-half lt, lies against the rip-roof side of the half 11.

By employing the novel construction herein shown and described, the guard may be easily and inexpensively manufactured, may be sold at small cost, may be quickly and easily applied at intervals during the laying of a shingle root, and when so applied, will be eliicient to hold snow against sliding from the roof. The construction of the snow stop 19,, with its lower portion 13 coiled about the arch 8, gives an exceptionally strong construction and moreover this stop is ellectively supported by the brace 10 and the base portion 9 with which the lower end of said brace is connected.

I claim A snow guard comprising a single length oi wire having a straight end portion constituting a shank for anchorage upon a roof, the wire at the lower end of said shank being arched and then extended on a straightline in a down-roof direction from the arch, :lorining a base portion to rest on the roof, the wire being bent upwardly at an acute angle at the lower end ofsaid base portion to provide a brace, said wire being curved laterally in one direction and downwardly from the upper end 01 the b ace to the aforesaid arched portion and being coiled tightly around this portion to form one half of an annular snow stop, the wire being then curved laterally in the other direction and upwardly from the coil to form the other half of said annular stop, the free end of said wire lying against the up-rooit side of the first named stop half.

in testimony whereof I have hereunto atiixed my slgnature.
